Everyone should turn off the power before changing the lights. This is a very important security protection. Don't think that just changing a light won't cause too much problem, but often the problem appears in this idea. Then, after turning off the power supply, we need to check what the problem is, whether the light bulb is broken or the wiring of our lamps is in poor contact.

Because the ceiling lamp specifications are suitable, so don't pry it down with a screwdriver or something, because it is easy to distort the original shape, and the biggest fear is that it can't be put back, so try to use professional tools to change the lamp. If you can't handle it yourself, you must ask a professional to change it.

After checking the problem, it is the last step. If the light bulb is broken, then everyone needs to take off the lampshade and put on a new light bulb. Or you can buy a special sucker in the market and use it to suck the next board. You need to do all four corners once, so you can take them off directly, and the price of this sucker is quite cheap.
